HAY-CARRIER.

JIJEIFICATION forming part of Letters Patent No. 334,917, dated January 26,1886.

Application filed October 21, i885. Serial No. 180,686. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK A. WHITE, of Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Hay-Garriers, of which the following is a specification.

This invention relates to that class of carriers which are employed for lifting hay or like material from the wagon or its equivalent, carrying the same to and depositing it at a distant point.

It is the aim of the invention to simplify the mechanism, render the same certain in its action, and adapt it to be readily reversed, in order to deposit the hay to the right or the left of the point from which it is lifted,as occasion may require.

In the accompanying drawings, Figure l represents a longitudinal vertical section through the center of my apparatus as it appears during the lifting of the hay, the parts being adjusted to move to the left. Fig. 2 represents a like section of the apparatus with the parts in the positions they occupy during the movement of the carriage. Fig. 8 is a top plan view of the parts in the position represented in the preceding figure. Fig. 4 is a transverse ver tical section on the line x of Fig. l. Fig. 5 is a vertical cross-section on the line g/ y ot' the same figure.

In constructing my apparatus I first provide two horizontal or approximately-horizontal rails, A, of any appropriate length, and arrange them parallel with each other in an elevated position. On these rails I mount a traveling carriage, B, consisting, essentially, of two vertical side plates, a, provided with carrying-wheels b, attached to the outer ends of two horizontal axles, c, which are extended horizontally through the plates. In the lower part of this frame, on a horizontal axle, I mount a grooved pulley, d, to receive the hoisting-rope C, and above this pulleyI mount a horizontal brake or clamp, c, designed to lock the hoisting-rope and maintain the hayfork or sling in its elevated position during the movement ofthe carriage over the rails to the place of deposit. This brake, which is automatic in its action, consists of a horizontal bar toothed or serrated on its lower edge, and sustained at its ends by links f, the upper ends of which are mounted loosely on the axles c,

[ so that when the bar is released it will drop by gravity upon the hoisting-rope.

Then the parts are adjusted for the transfer of the hay to the left of the hoisting-point, the links stand with a downward inclination to the left, as shown in Fig. l, so that they will permit the rising of the brake and the free movement of the hoistingrope to the left, but urge the brake forcibly downward, so as to lock the rod whenever the latter tends to move to the right. This arrangement permits the fork or sling to be hoisted with out resistance, but causes it to be autom-ati cally locked in `suspension when the hoist ing-rope is slack or the carriage released. In order to insure the action of the brake, it is provided on its two sides with depending ngers (j, and the pulley d provided on its side faces with lugs or studs h, to engage said fingers, and thereby draw the brake forcibly downward whenever the pulley d receives a reverse motion from the hoisting-rope. Vhile the hoisting-rope is in position, it prevents the brake-links from passing to the right of the vertical; butthe removal of the hoisting-rope, which is commonly effected by a small line attached to its end, will permit the brake and links to swing to the right, as indicated by dotted lines in Fig. l, so that when the rope is replaced the plates will act to check its motion to the left, instead of to the right under the first adjustment. In this manner the parts are adapted to deposit the hay at the right instead of the left of the liftingpoint.

For the purpose of locking the carriage in position during the time that the load is being lifted, and automatically unlocking it that it may travel tothe point of deposit at the completion of the lifting action, and this 1 whether the movement is to the right or the left, I attach to the rails stationary grooved plates i, and provide the carriage with two st-irrups, llc-one at each end-to engage with the plates. Each stirrup has at the lower end a circular ring for the passage of the hoistingrope, with two arms rising therefrom on oppo site sides, and provided at their upper ends with horizontal rollers Z, extended outward through vertical slots in the side plates ofthe carriage, in order to engage the shoulders formed in the stationary plates t'. As shown in Figs. 1, 3, and 5, each of the stationary IOO plates is provided'with a longitudinal groove rising from the two ends toward the center, where it is cut downward to form a notch or shoulder, i. It is in these shoulders that the rollers Z of the carriage engage.

When the carriage is moved from either di-` this time the parts stand in the position shown in Fig. 1. During the hoisting operation the position of the parts remains unchanged until the fork or sling reaches the proper elevation, when it encounters the lower end of the link lc, raising the same so as to force its rollers out of engagement with the shoulder i', whereupon the strain of the rope causes the carriage to move to the left. As the movement of the carriage'commences, the brake, relieved from the action of the plates i, descends upon the rope, and, locking the same against back ward motion over the pulley, holds the hay at the proper elevation until the carriage reaches the point at which it is to be deposited. When this point is reached, the hay is discharged by tripping the fork or sling in the usual manner. The carriage is then permitted to return by gravity,if the rails are inclined,or drawn backward by an attached line, if the rails are horizontal, to its original point, where it is again locked by the stirrup, and the brake alitomatically lifted so that the hoisting-rope may be lowered.

It is to be observed that the brake is maintained out of action whenever the carriage is locked in position, and that during this time the hoisting-rope is free to move in both directons.

In the foregoing I have described that operation of the parts which takes place in carrying the hay to the left. When the parts are adjusted for transferring the hay to the right, they will operate in like manner, except that the brake will be adjusted to the right, as before described, and that the carriage will be locked by the stirrup at the left end. But one stirrup is in use at a time, the two being employed in order to permit the action to the right or left, as may be required.

In order to insure the engagement of the locking-rollers in the shoulders i', I provide each plate with a downwardly-extending shoulder, i2, directly over the notch i', as shown in Fig. 2. This compels the descent of the roller into the notch, and prevents it from passing by the same without engagement, as might otherwise occur.

The provision of the rollers on the stirrups to engage the locking-plates is found in practice to be highly advantageous, since it permits their smooth and easy disengagement, and this avoids the excessive strain which would otherwise be required to effect the unlocking of the carriage, as well as the violent shock which would result from its sudden release.v

Having thus described my invention, what I claim isl. In a hay-carrier, the Wheeled carriage provided with the pulley d, in combination with the brake and its two sustaining-links.

2. In a hay-carrier, the Wheeled carriage having the pulley d therein, in combination with the brake-bar and its sustaining-links, reversible astoinclinatiomas described.whereby the brake is adapted to hold the hoistingrope against movement in either direction, as may be demanded.

3. In combination with the carrier-frame and the pulley having studs or teeth, the pendent links and the brake-shoe having arms to engage the studs of the pulley, whereby the pulley is caused to assist in' operating the brake.

4. In combination with the carriage provided with the pulley, the brake, and a lockingstirrup,the rails and the stationary plates, adapted, as described, to disengage the brake, and provided with the notches to receive the stirrups.

5. In combination with the carriage provided with stirrups or locking devices, the fixed plates provided with the notch t' and the shoulder i2 thereover.

6. In a hay-carrier, the carriage provided with the stirrups having the rollers, in com- FREDERICK ASA WHITE.
